Definitions
- the invention relates to a pump assembly having at least one water pump and a controller for the speed thereof, wherein the pump is designed for circulating water in biological waters subject to influences such as ponds, aquariums or fountains.
- Such pumps can both serve to power filters as well as water games or Fontainen operate and / or improve the gas exchange and oxygenation in other ways and cause in winter by circulation protection by the water before freezing.
- Waters or water containers in which such pumps are used may be exposed to biological influences due to changing outdoor and water temperatures. Further biological influences are, for example, a degree of turbidity of the water body, possible pollutant load, change in the oxygen content or the like.
- the invention is therefore an object of the invention to provide a pump assembly whose ease of use is increased and makes energy savings possible.
- the object on which the invention is based can be achieved by modifying a temperature control for the special field of use of pumps for biological influences subjected to water or water containers and supplemented by an electronic control system, a data memory and a control software.
- this is designed to set a maximum temperature limit from which the controller will control the pump to operate at maximum speed, and set a minimum temperature limit below which the controller will not further lower the speed of the pump, but increase it.
- the pump automatically increases the speed within the temperature range between the two limits as the temperature increases, while at temperatures below the minimum temperature stored in the memory, the speed and, thus, the recirculation level of the pump increases again rather than being lowered further.
- the pump assembly is particularly comfortable to use and flexible in the application equipped by the controller has control electronics and a data memory with a control software.
- the control software may also be replaced as needed when basic water conditions, e.g. whose size, the amount of fish stocking, the vegetation or other climatic or biological conditions change seriously.
- a temperature limit value is stored as the maximum temperature, from which onwards and at temperatures above that, the controller always runs the pump at maximum speed.
- partial load temperature limits may be specified in which a stepped adjustment of the pump speed takes place.
- a possible energy-saving design of the pump could be chosen so that at water temperatures of 6 to 8 ° C, a minimum amount of water of 3,500 l / h is circulated. At temperatures between 8 ° C and 20 ° C, the amount of water and the degree of recirculation could be increased continuously or in steps. For example, an average speed at temperatures between 15 and 18 ° C may be provided. From a temperature limit of 20 ° C, the pump should then run at maximum speed for maximum circulation.
- the pump arrangement according to the invention is preferably used in pumps with an electronically commutated drive (EC pumps). It is particularly advantageous to integrate the controller and the temperature sensor directly into the pump. But it is also possible, an external electronics and / or sensors which can also be operated with conventional asynchronous or synchronous pumps.
- EC pumps electronically commutated drive
- the pump shown has a housing 1 with an intake 2, through which the water enters the pump, and a discharge nozzle 3, through which the water leaves the pump again.
- the water is conveyed via an impeller 4, which is driven by a shaft 5 by an electric motor 6.
- the electric motor 6 has a rotor 7 which is rotated by an electromagnetic field formed from electric coils 8 in rotation.
- a split tube 9 separates the area 1 'of the housing 1, through which water flows, from the electrical housing area 1 "which is to be kept dry.
- control electronics 11 are also disposed in the electrical area 1" via which the rotational speed of the motor and thus also of the pump is regulated.
- a temperature sensor 12 is also arranged, which measures the temperature of the water conveyed past him at the position of the arrow 13.
- the temperature sensor 12 is connected in a manner not shown to the control electronics 11.
- the temperature sensor 12 is arranged so that it absorbs as little heat of the pump as possible in order to perform a largely unaffected water temperature measurement can.
- a particularly advantageous position of Temperature sensor 12 is in the Fig. 1 and 2 shown.
- the arrangement of the temperature sensor 12 is chosen so that it is located exactly in the transition between the water-carrying area 1 'of the housing and the electrical area 1 "of the housing dry connection to the control electronics 11 in the electrical range 1 "of the pump is possible.
- the temperature sensor 12 is received in the flange of the can 9. This position is optimized by arranging the temperature sensor as far away as possible from each of the coils 8 of the pump motor 6. In the case of coils 8 arranged in a star shape, such an advantageous position of the temperature sensor 12 is located exactly in the middle in a free segment between two coils (see FIG. Fig. 2 ).
- a switch 14 On the upper side of the housing is accessible from outside a switch 14, via a connection, not shown, to the control electronics 11, the control in response to the temperature measured at the temperature sensor 12 water temperature can be switched on or off. This switch can therefore be switched between manual control and automatic operation.
- the entire pump arrangement may also include further sensors, for example for detecting the water turbidity or the current oxygen content. These signals can also be evaluated by the control electronics and incorporated via the control software in the speed control.
- the control electronics since the most important influencing factor is the water temperature, pump arrangements which have only one temperature sensor are already very effective and save considerable energy compared to conventional, manually controlled pumps by always optimal operation. Such pump assemblies are operated year-round with almost no maintenance and effort.
- Their control software can be termed, so to speak, an annual biology program, as it automatically adjusts pump performance to the seasons and the resulting operational needs.
- the control software can take account of other calendar-related or daytime-dependent influencing factors and thereby even better fulfill the pump to the needs of the operator and the water in which it is used.
